MEANS FOR SUPPORTING ELECTRIC MOTORS.

SPECIFICATION forming part of Letters Patent No. 61 1,273, datedSeptember 27, 1898.

Application filed May 14, 1897. Renewed February 23, 1898; Serial No.671,331. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS T. PYOTT, a citizen of' the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain 'to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates'to the supporting of motors upon the trucks ofrailway-cars propelled by electricity; and the objects of my improvements are to provide an elasticsuspension to carry the motorwithout jars and shocks, to perform the work in a simple and easy mannerwith few parts, and so applied that the motor can readily be attached toor removed from the truck by the simple unscrewing of a few nuts.

I attain the objects of my invention by the:

mechanism illustrated in the accompanying drawings, in which Figure l isan elevation View showing the motor-casing, its suspension, and thecrosspieces, to which the suspension-hangers are attached, and thetruck-frame in cross-section. Fig. 2 is a plan showing the same parts.Fig. 3 is an enlarged side view of the suspension-hanger. Fig. 4 is aplan of Fig. 3, while Fig. 5 is a front view of the same. Fig. 6 is aside elevation of one of the motor suspensions, showing it attached tothe motor-case 5 and Fig. 7 is a plan of Fig. 6.

In each view like figures of reference indicate like parts.

Motors have heretofore been suspended upon side lugs removed from theaxle-sup port, but not in manner as here shown. In Fig. 1 one end of thecasing 1 has bearings 2 formed to embrace the axle 3, whereon arelocated the wheels 4, upon which the truck is carried on the rails, andlugs 5, being cast upon each side of the motor-casing, preferably underor over the armature-shaft 6, according to the size of motor, andreaching outward, have heretofore been inserted in levers which bynumerous fulcrums, links, le-

vers, and other appliances were finally supported by the truck-frame,generally upon coiled or rubber springs. The numerous parts employed insuch instances made it a matter of much work and difficulty to put up ortake down the parts when a motor required to be attached to or removedfrom the truck, and the springs which with such construction werenecessarily employed are not of a form ,to have the flexibilitydesirable for easy car- 8 projecting beyond the body of the box.

The box is of rectangular shape and is embraced at its top and bottomsides by a loop 9 formed on one end of the suspension member 10, theloop being long enough to allow a movement overthe box 7 withouttouching its ends. The suspension member 10 is a single-ended springhaving a band 11 near the opposite end from the loop 9, which embracesand secures the plates 12, of which it is composed, and all of whichwork in unison when yielding and all of which assist in supporting theplate forming the loop 9 and on which the box 7 rests. Plates 12 extendsomewhat beyond band 11 for the purpose hereinafter described.

Suspension member 10 is secured in a pocket 13, formed in the lower partof bracket 14, secured to and supported by cross-tie 15, which also inthis instance rests upon and is secured to the framework 16 of thetruck. The pocket 13, in which the suspension member 10 is secured, isopen at the side 17 and is recessed at its top, bottom, and back toadmit the band 11, and is then contracted, as at 18, to touch plates 12,thus preventing end movement of the suspension member 10, it

being held sidewise in the pocket 13 by the' hooked bolt 19, which isplaced in a groove 20 in bracket 14 and going down underneath thebracket is bent to pass under it in groove 21 and then is turned upwardfor a distance upon the inner side of the bracket 14. By an examinationof Fig. 2 it will be seen bolt 19 passes down by member 10 and band 11in the angle formed by the end of band 11 and outer side of suspensionmember 10, thus preventing any movement when the bolt 19 is in itsplace. Bolt 22 is similarly located at the opposite end of band 11,passing through lugs 23 and against the sides of the plates 12, whichproject beyond the band 11 at 24. The bracket 14 is shown attached tocross-tie 15 by bolt 25, assisted by lug 26 and shoulder 27. It willreadily be seen that by lengthening the bracket 14 upon cross-tie 15more bolts might be applied. The bracket is also shown reaching back andengaging truckframe member 16, lugged upon its top at 27 and secured bybolt 28. This construction is such as I have applied to the companionsectional truck patented to me January 12, 1897, No. 593,742; but inother forms of trucks not having such a construction as here shownwhereon to attach the bracket 14 I can just as readily apply my form ofsuspension, as a bracket suitably constructed to attach to any cross-tieadapted to reach across and suitably formed to be secured to any of thevarious forms of truck-frames is all that is essential to apply my formof motor suspension.

By reference to Figs. 1 and 2 it will be seen that pockets 13 openoutward in brackets 14 of the opposite sides in opposite ways, the openside 17 being'toward the outside of the truck, so that all that isnecessary to remove the motor suspension is to unscrew the nuts of bolts19 22 and remove the bolts, when the suspension members 10 can beremoved from their pockets 13 and off of lugs 5 with much less work thanwith any other form of suspension heretofore known or used, and I havecheapened the cost of construction by eliminatin g various small partsworking upon each other on delicate bearings liable to rapid wear frombeing exposed toflyin g dirt constantly stirred up under the car-body asit moves along over the roadway. I have illustrated a motor-casing withside lugs below the armature-shaft and the axle; but in some forms ofm0t0r-casi11gs the suspension-lugs are at a point above thearmature-shaft and the axle, and if the same form of truck as I haveillustrated was then used I would rest the bracket upon and above thecross-tie, and it would as readily support the flexible motor-casing asin the arrangement shown, it being merely an adaptation of my inventionto suit the varying construction.

Having described my invention, I claim- 1.
